The PEMA 4125.70 is engineered to significantly reduce system costs, minimize spatial footprint, enhance energy efficiency, and streamline both installation and programming processes.

Available in both four and eight-channel configurations, with power options of 125 and 250 Watts per channel, the PEMA 4125.70 caters to a variety of sound system requirements. It boasts full 96kHz performance, powered by 32-bit SHARC processors, ensuring your audio is delivered with absolute clarity and transparency.

The PEMA 4125.70 is a game-changer for sound system consultants and integrators, simplifying design with its comprehensive features. It requires only input sources and output speakers to provide an elegant audio solution, reducing the need for extensive cabling, rack space, and installation time. The amplifier leverages proven DSP and amplifier technology to deliver an audio experience that impresses with its simplicity and reliability.

Equipped with advanced DSP algorithms, the PEMA 4125.70 offers ambient noise compensation, automatic feedback suppression, an automatic mixer, and a full suite of filters, EQs, delays, and more. Amplifier functionality is also DSP-controllable, including bridge-mode operation, high-pass filter settings for constant voltage systems, stereo-linking of channel pairs, and comprehensive remote-gain control capabilities.

The PEMA 4125.70's input/output count and formats are perfectly suited for small to mid-sized installations. It features eight balanced input channels, software-selectable for mic or line levels, with the first channel also configurable for transformer-isolated TEL-PBX level. Additionally, eight pairs of summed-mono RCA connectors are optimized for consumer line-level devices. Eight preamp auxiliary outputs provide flexibility for signal routing within the system.

As part of the respected Protea DSP family, the PEMA 4125.70 is remarkably user-friendly in terms of programming and deployment. Setup is achieved using standard 10/100 Ethernet protocol and Ashly's Protea ne Software on a PC platform. Hot-plug DSP placement and automatic DHCP network IP configuration simplify network setup, while lockable front panel controls and multi-level software security with password access ensure a secure audio system.

The PEMA 4125.70's architecture and engineering specifications are meticulously crafted. Each input channel includes a summed stereo and mic/line gain stage, with selectable phantom power. The unit's processing blocks are highly configurable, offering dynamic control, gain adjustments, equalization, crossover, delay, metering, and signal generation. The matrix mixer allows for flexible input-to-output assignment and gain-sharing automatic mixing.

Four powered outputs deliver precise wattage with the option to bridge channel pairs for increased power. The frequency response is impressively flat across the audible spectrum, and the signal-to-noise ratio exceeds industry standards. LED indicators provide real-time status monitoring, and front panel volume controls offer easy adjustments when enabled.

Control and programming are accessible via the rear panel RJ-45 jack, connecting to a LAN and managed with Ashly's Protea NE Software. The unit includes thirty internal presets and four scenes accessible via contact closure. Optional Cobranet and Dante factory options expand the unit's connectivity, while a contact closure can place the unit in "Standby" mode for energy savings. The temperature-controlled fan ensures optimal operating conditions, and the unit's lightweight design allows for easy integration into standard 19" racks.

The PEMA 4125.70 is a Protea Equipped Media Amplifier model that supports Microsoft Windows 8, 7 (Vista/XP) 32 & 64-bit systems, offering audio professionals an intuitive and navigable DSP experience. With the PEMA 4125.70, you are not just purchasing an amplifier; you are investing in a seamless, high-fidelity audio system that stands at the pinnacle of technological advancement.
